When did the Subaru Impreza switch to timing chain?
The Subaru Impreza, a popular compact car, has transitioned from a timing belt to a timing chain design for its engine. This change occurred in the mid-2000s, providing improved reliability and longevity for Impreza owners.
The Timing Belt to Timing Chain Transition
Traditionally, the Subaru Impreza had been equipped with a timing belt, a rubber-based component that required periodic replacement to ensure proper engine operation. The timing belt's lifespan is typically around 60,000 to 90,000 miles, after which it needs to be replaced to avoid potential engine damage.
However, in the mid-2000s, Subaru made the decision to switch the Impreza's engine design to a timing chain. A timing chain is a metal chain that connects the crankshaft to the camshaft, and it is generally more durable and longer-lasting than a timing belt. The timing chain is designed to last the lifetime of the engine, eliminating the need for periodic replacement.
Benefits of the Timing Chain
The transition to a timing chain in the Subaru Impreza offers several advantages for owners:
- Improved Reliability: Timing chains are less prone to wear and tear compared to timing belts, reducing the risk of unexpected failures and engine damage.
- Reduced Maintenance Costs: With no need for periodic timing belt replacement, owners can save on the associated labor and parts costs.
- Longer Engine Life: The timing chain's durability can contribute to the overall longevity of the Impreza's engine, providing a more reliable and long-lasting driving experience.
The switch to a timing chain design in the Subaru Impreza has been a positive change for the model, enhancing its reputation for reliability and reducing the maintenance burden for owners.
What year did Subaru go to timing chain?
Simply, then, a 1997 to 2011 Forester will have a timing belt, while any of the fourth-gen Foresters (from 2013 or later) will have a timing chain. And for a brief period from 2011 to 2012, the Forester was fitted with either a timing belt or a timing chain depending on which engine was fitted.
What year did Subaru stop using timing belts?
2011 was the first year for the newest version of the 2.5L normally aspirated engine. Years previous to 2011 the 2.5L, as did all Subaru flat four engines, used a timing belt. Beginning in 2011 the 2.5L uses a timing chain.
What Subaru models have a timing chain?
All Foresters from 2011 onward (2014 for the XT) have a timing chain.
Does a 2009 Subaru Impreza have a timing belt?
For example, the 2009 Subaru Impreza owner's manual recommends timing system inspections every 30,000 miles and having the timing belt replaced every 105,000 miles. Failure to change the timing belt on time could lead to a timing system failure.
Does the 2017 Impreza have a timing belt or chain?
They don't have a timing belt. There is a chain and the seals don't last as long as the chain so it is not a maintenance item anymore.
Does a 2018 Subaru Impreza have a timing belt or chain?
The GEN5 Impreza has only a single belt. It drives the alternator and AC compressor. There is no timing-belt and instead has timing CHAIN which should last well over 150K miles if oil is changed regularly.
Does a 2015 Subaru have a timing chain?
This Fits Your 2015 Subaru Impreza. Your engine's timing chain can stretch over time resulting in a check engine light that comes along with excessive noise from your engine's timing cover. If the chain has broken, which is a rare occurrence, the engine will not start.
Does a 2008 Subaru Impreza have a timing belt or chain?
This Fits Your 2008 Subaru Impreza. Your timing belt is typically replaced as part of a scheduled service. A failed timing belt can result in anything to an engine that will crank but not start to catastrophic engine damage.
Does a 2015 Subaru Impreza have a timing belt?
Newer models use timing belts made of polyurethane and Kevlar for long life and durability. They can go as long as 100,000 miles although it's always a good idea to change it before then. Belt failure can cause extensive damage to the valves, pistons and other internal parts of the engine.
What years did Subaru have CVT problems?
The models and years that were affected mainly by transmission issues are:
- Crosstrek, 2013 – 2015.
- Crosstrek Hybrid, 2014 – 2015.
- Forester (2.0 and 2.5 liter engines), 2014 – 2015.
- Impreza, 2012 – 2015.
- Legacy, 2010 – 2015.
- Legacy 3.6L V6, 2015.
- Outback, 2010 – 2015.
- Outback 3.6L V6, 2015.
